Pro-Russian actors flooding newsrooms with fake content to overwhelm fact-checkers

Pro-Russian actors are inundating newsrooms with false information in a strategic attempt to overwhelm verification resources and amplify the spread of disinformation, new study says.

The identified scheme is part of a global ongoing operation dubbed “Operation Overload.” It involves anonymous pro-Russian actors systematically contacting journalists through emails and social media, urging them to verify suspected fake news. The goal is to stretch fact-checkers thin and to ensure the false narratives reach wider audiences, whether debunked or not.

The operation has targeted over 800 news organizations across Europe and outside of the European Union, disseminating around 2,400 tweets and more than 200 emails, with the majority of messages containing misleading links hosted on the messaging app Telegram.

Attackers use new tactics in campaign targeting exposed Docker APIs

Cybersecurity researchers have uncovered a sophisticated malware campaign targeting publicly exposed Docker API endpoints, aiming to deploy cryptocurrency miners and other malicious payloads.

The new campaign, detailed by cloud analytics platform Datadog, bears similarities to another operation named “Spinning YARN” detected in March 2024 by cybersecurity firm Cado Security. The campaign targets misconfigured services like Apache Hadoop YARN, Docker, Atlassian Confluence, and Redis for cryptojacking.

Cybercriminals use new social engineering tactic for running PowerShell and installing malware

A threat actor known as TA571 and the ClearFake activity cluster have been observed employing an innovative social engineering technique designed to manipulate users into executing malicious PowerShell scripts and infecting victim devices with malware.

Rust-based Fickle Stealer distributed via multiple attack chain

A new Rust-based information-stealing malware called ‘Fickle Stealer’ has been discovered that is being distributed through multiple attack chains. Fortinet FortiGuard Labs reports four distinct methods of delivery: VBA dropper, VBA downloader, link downloader, and executable downloader. Some of these methods employ a PowerShell script to bypass User Account Control (UAC) and execute the malware, aiming to harvest sensitive information from compromised systems.

Highly evasive SquidLoader malware is targeting Chinese orgs

LevelBlue Labs released a report on a new highly evasive loader, named “SquidLoader,” delivered through phishing attachments to specific targets. SquidLoader, a type of malware used to load second-stage payloads onto victim systems, employs various evasion techniques to avoid analysis. First observed in late April 2024, SquidLoader likely had been active for a month prior. The retrieved sample revealed it delivered a modified Cobalt Strike payload. The actor behind SquidLoader has been running sporadic campaigns over the past two years, mainly targeting Chinese-speaking victims.
